ROOT RAKE Thomas W. Peacock and George W. Peacock, Sr., Jacksonville,Fla., assignors of one-half to John E. Price, J acksonvllle, Fla.

Application July, 25, 1941, Serial No. 763,634

5 Claims- (Cl. 37-2) The invention, which relates to root rakes orgrubbers, has for its objects to improve the grubber disclosed in theapplication of John E. Price and Thomas W. Peacock, Serial No. 634,967,filed December 14, 1945, so as to enable a more successful and extendeduse of the same by cutting downbreakage of the teeth and shearing of themounting bolts.

To the attainment of the aforesaid objects, in-v vention resides in theconstruction, combination and arrangement of parts hereinafter firstfully described and then specifically pointed out in the appendedclaims, reference being had to the accompanying drawing in which:

Fig. 1 is a perspective view of the improved rake.

Fig. 2 is an enlarged perspective view of one tooth viewed from therear.

Fig. 3 is a cross section on the line 3-3 of Fig.2.

Fig. 4 is Fig. 2.

In the drawing in which like numerals and letters of reference indicatelike parts in all the figures, I represents the side posts or standardsof the rake frame, 2 the ears for attachment to the pivoted yoke arms ofa known tractor and 3 the members with which the lifting arms of thetractor are adapted to be connected. The side standards I havereinforcing ribs 5, 5 on their front faces between which ribs an angleiron 4 is located and welded to each standard I and its ribs 5, 5 at w.One part of the angle iron 4 lies parallel to the standards I, i. e.. ina vertical position while the other part lies horizontal as best shownin Fig. 1.

Secured to the standards I adjacent their lower ends is a cross beam Ilcomposed of two angle irons welded together to constitute a tubular beamsquare in cross section. One edge of this beam is welded to thestandards, see Fig. 1, the opposite edge being at the front. The beam isso positioned that a plane intersecting the front and back edges Il Ilwill lie horizontally.

Each tooth of the rake being of the same construction, a description ofone will suflice. The tooth comprises an. upper portion 6, anintermediate portion 8 and a lower portion 9. The upper and lowerportions have strengthening ribs 1 and I respectively at the rear.

The intermediate portion, at the rear, has a right angled seat II, thefaces of which lie at approximately forty-five degrees to the horizontalso as to receive a mounting pad having two a cross section on the line4-4 of parts I4 and I which lie at right angles to each other. The upperpart I4 is provided with bolt holes I6 for the bolts, with nuts I9, thatsecure the pad I4-I5 to the beam H as shown in Fig. 1. Welded to the ribI at its upper end is a second or top mounting pad I2 composed of a flatplate to lie against the vertical face 4 of the angle iron 4 to whichthe plate is secured by bolts and nuts I9", the bolts passing throughholes I3 in 'the plate I2 and through registering holes in the angleiron beam 4.

The ends of the beam H are closed by plates I8 welded in place toprevent dirt and moisture entering the beam.

Experience has shown that, with the construction shown in the aforesaidapplication Serial No. 634,967, the securing bolts sometimes shear offthereby permitting the teeth to drop off. This is especially true whenthe grubber is used in heavy growth. With the present construction wehave found that the danger of shearing the attaching bolts has beenentirely eliminated.

By providing the mounting pad I4, I5 and securing it integrally to thetooth proper the up thrust which, in the structure involved in the aboveapplication, was taken solely by the relatively short extension of thetooth below the lower transverse angle beam of the frame, is now takenin part by the intermediate portion of the body of the tooth and theremainder by the rib. As the pad I4, I5 is wider than the tooth severalbolts I9 may be provided to hold the tooth to the beam I'I. Likewise theprovision of the mounting pad I2 which is wider than the body of thetooth allows for additional bolt protection.

From the foregoing description taken in connection with the accompanyingdrawing it is thought the construction, operation and advantages of theinvention will be clear to those skilled in the art.

What we claim is:

1. A root rake comprising a supporting frame having uprights at thesides, an upper horizontal angle iron integrally secured to saiduprights to lie in front of the same with one portion of the angle ironin a horizontal plane and the other portion of the same in a verticalplane, a tubular cross beam of a rectangular cross section having oneedge integrally united to said uprights, at least one tooth having anL-shaped saddle intermediate its ends to fit said tubular cross beam,bolts with nuts passing through said saddle and said tubular beam andrigidly securing said saddie to said beam, said tooth adjacent its upperend having a pad to lie against said angle iron, and

bolts and nuts securing said pad to said angle 2. A root rake toothcomposed of an upper portion, a lower portion and an intermediateportion,

- and lower portions each including a front face and a back rib, a flatmounting pad integrally secured to the back rib of the upper portion ad-Jacent its upper extremity, and a mounting pad of two integral parts atright angles to each other integrally secured in the seat of saidintermediate portion and to said back ribs.

3. A root rake tooth composed of an upper portion, a lower portion andan intermediate portion, the intermediate portion having a seat on itsrear face which seat is composed of two faces at right angles to eachother and lying at approximately forty-five degrees to a vertical plane,said upper and lower portions each including a front face and a backrib, a flat mounting pad in- 1 tegrally secured to the back rib of theupper portion adjacent its upper extremity, and a mounting pad of twointegral parts at right angles to each other integrally secured in theseat of said intermediate portion and'to said back ribs, combined with aframe having side standards, an upper angle beam with a vertical faceand a lower beam of square cross section to receive and fit saidtwo-faced mounting pad, said mounting pads being wider than the body ofthe tooth proper and each being provided withbolt holes, and bolts andnuts securing said pads respectively to said beams.

4. A root rake comprising a suporting frame having upright sides, anupper horizontal angle iron integrally secured to said uprights to liein front of the same with one portion of the angle iron in a horizontalplane and the other portion of the same in a vertical plane, a crossbeam of rectangular cross section the faces of which lie at an angle tothe horizontal, one edge only of the cross beam being integrally unitedto said uprights at the front of the same, at least one tooth having anL-shaped saddle intermediate its ends to fit on the two front faces ofsaid tubular cross beam, means passing through said saddle and into saidcross beam rigidly securing said saddle to said cross beam, said toothadjacent its upper end having a pad to lie against said angle iron, andmeans securing said pad to said angle iron.

5. A root rake comprising a supporting frame having upright sides, anupper horizontal angle iron integrally secured to said uprights to liein front of the same with one portion of the angle iron in a horizontalplane and the other portion of the same in a vertical plane, a crossbeam of rectangular cross section the faces of which lie at an angle tothe horizontal, one edge only of the cross beam being integrally unitedto said uprights at the front of the same, at least one tooth having anL-shaped saddle intermediate its ends to fit on the two front faces ofsaid tubular cross beam, means passing through said saddle and into saidcross beam rigidly securing said saddle to said cross beam, said toothadjacent its upper end having a pad to lie against said angle iron, andmeans securing said pad to said angle iron, said tooth having a back ribconnecting said pad to the top of said saddle and having a second backrib connected to the bottom of said saddle and extending toapproximately the bottom of said tooth.
